Roof Installation Services We Provide

From traditional asphalt shingles to premium slate and modern solar systems, our roof installation services cover every roofing type available in today's market. Each installation follows manufacturer specifications and local building codes, which ensures your new roof performs exactly as designed for decades to come.

We install GAF Timberline HDZ and Owens Corning Duration shingles that last 15 to 30 years and currently hold over 70 percent market share nationwide. These cost-effective systems range from $3.50 to $5.50 per square foot and provide reliable protection for most residential properties in our service area.


Our installation process includes proper underlayment, ventilation setup, flashing integration, and ridge cap finishing that manufacturers require for full warranty coverage. You'll receive a roof that handles California weather patterns while maintaining curb appeal and meeting all local code requirements for wind and fire ratings.

Metal Roofing System Installation

Metal roofs from brands like Drexel Metals and ATAS International offer 40 to 70 years of service with wind resistance up to 140 mph. These systems use steel, aluminum, copper, or zinc materials that cost between $6 and $12 per square foot depending on your chosen profile.


Installation involves precise panel alignment, thermal expansion accommodation, concealed fastener systems, and specialized trim work that prevents leaks and noise issues common with improper installs. Your metal roof will reflect solar heat to reduce cooling costs while providing a modern aesthetic that increases property value significantly.

Clay and Concrete Tile Roof Installation

Spanish and Mediterranean-style properties benefit from our tile roof installations using Boral Roofing and Eagle Roofing Products that last 40 to 100 years. These beautiful systems cost $8 to $18 per square foot but weigh up to 1,000 pounds per roofing square, which requires structural evaluation before installation.


We reinforce framing as needed, install proper underlayment rated for tile applications, secure each tile according to high-wind specifications, and integrate custom flashing systems. The result is a distinctive roof that withstands intense sun exposure, resists fire damage, and maintains its appearance for generations without fading or deteriorating.

Flat Roof Installation for Commercial Buildings

Commercial properties need reliable flat roof systems like TPO, PVC, and EPDM from Carlisle SynTec and Firestone Building Products that last 20 to 30 years. These membrane systems cost $4 to $7 per square foot and provide watertight protection for buildings with minimal roof pitch or large surface areas.


Our installation includes proper drainage design, seam welding or adhesive bonding, penetration flashing for HVAC units and vents, and edge details that prevent wind uplift. You get a roof that handles foot traffic for maintenance access while protecting your building contents from water damage and supporting equipment loads safely.

Understanding Our Roof Installation Material Options

Choosing the right roofing material affects your building's protection, appearance, and long-term costs for decades after installation is complete. Each material type offers specific advantages depending on your building's architecture, your budget parameters, local weather patterns, and your aesthetic preferences.

Premium Slate Roofing Installation


Natural stone slate from Vermont Slate Company and Buckingham Slate lasts 75 to 200 years with fireproof properties and unmatched elegance. These premium installations cost $15 to $30 per square foot and require specialized cutting, drilling, and fastening techniques that few contractors master properly.


Synthetic Composite Roof Installation


Products from DaVinci Roofscapes and Brava Roof Tile mimic natural materials while offering 40 to 50 years of performance at $8 to $12 per square foot. These lightweight alternatives install faster than authentic materials and use recycled content that appeals to environmentally conscious property owners looking for sustainable building solutions.


Natural Wood Shingle and Shake Installation


Cedar, redwood, or pine roofs from Watkins Sawmills and the Cedar Shake and Shingle Bureau provide 20 to 40 years of natural beauty. Installation costs run $6 to $9 per square foot and requires proper ventilation underneath to prevent moisture damage and premature decay in our climate.

Our Roof Installation Process and Timeline

Every roof installation project follows a structured approach that ensures quality results, minimal disruption to your daily activities, and complete satisfaction with the finished product. From initial assessment through final cleanup, we maintain clear communication so you always know exactly what's happening with your investment in your property.

Initial Inspection and Material Selection


We start by evaluating your existing roof structure, measuring all roof planes, photographing current conditions, and discussing your goals for the new installation. This assessment reveals any structural issues that need addressing, determines the best material options for your building type and budget, and allows us to provide accurate pricing.


Permit Processing and Project Scheduling


Once you approve our proposal, we will handle all permit applications with local building departments, order your chosen materials from trusted suppliers, and schedule your installation date. This preparation phase typically takes one to three weeks, depending on material availability and permit office processing times in your jurisdiction.



Complete Tear-Off and Installation Work


Our crews arrive on schedule to protect your landscaping, remove your old roofing materials down to the decking, repair any damaged structural components, and install your new roof. Most residential installations take two to five days depending on roof size and complexity, while commercial projects may require one to three weeks.

Frequently Asked Questions

  • How long does a typical roof installation take to complete?

    Most residential roof installations take two to five days, depending on roof size, complexity, material type, and weather conditions during the installation period. Commercial projects or complex residential designs with multiple roof planes may require one to three weeks to complete properly without rushing critical installation steps.

  • What roofing materials last the longest in our climate?

    Slate roofs last 75 to 200 years, metal roofs provide 40 to 70 years of service, and tile roofs perform for 40 to 100 years. These premium materials cost more initially but offer the best long-term value by eliminating the need for multiple replacements over your building's lifetime.

  • Can you install a new roof over my existing shingles?

    Building codes in most California jurisdictions limit roof layers to a maximum, but we typically recommend a complete tear-off to inspect the decking for damage. Installing over existing materials hides problems, voids many warranties, adds excessive weight to your structure, and reduces the new roof's lifespan by trapping moisture underneath.

  • Do I need to be home during the roof installation?

    You don't need to be present during installation, but someone should be available for initial walkthroughs and final inspections to approve completed work. We'll need access to exterior outlets for power tools and clear pathways around your building for material delivery and debris removal throughout the project.

  • What factors affect roof installation costs the most?

    Material selection drives costs more than any other factor, with prices ranging from $3.50 per square foot for asphalt shingles to $30 per square foot for premium slate. Roof pitch, accessibility, number of penetrations, required structural repairs, and disposal fees for old materials also impact your total investment significantly based on your building's specific conditions.
